    ABSTRACT: Open data make it possible to set up multi-basin models for large domains across environmental, climate and administrative boundaries. This study presents new methods for evaluating a number of aspects of multi-basin model performance, while exploring the performance of the E-HYPE_v2.1 model for several evaluation criteria in 181 independent river gauges across the European continent. Embedded model assumptions on dominant flow generating mechanisms are analysed by correlating physiographical characteristics to the flow regime. The results indicate that the model captures the spatial variability of flow and is therefore suitable for predictions in ungauged basins. The model shows good performance of long-term means and seasonality, while short-term daily variability is less well represented, especially for Mediterranean and mountainous areas. Major identified shortcomings refer to the resolution of precipitation patterns, aquifer exchanges, water extractions and regulation. This will guide the work with the next model version for which improvements in input data, processes and calibration have been identified to potentially contribute most to improved model performance.

    ABSTRACT: This study assessed the performance of Fourier series in representing seasonal variation of tropical rainfall process in Malaysia. Fourier series is incorporated into a spatial temporal stochastic model in an attempt to make model parsimonious and at the same time, capture the annual variation of rainfall distribution. In view of Malaysia’s main rainfall regime, the model is individually fitted at two regions with distinctive rainfall profiles; one is an urban area receiving rainfall from convective activities whilst the other receives from monsoonal activities. Since both regions are susceptible to floods, the study focuses on rainfall process at fine resolution. Fourier series equations are developed to represent model’s parameters to describe their annual periodicity. The number of significant harmonics for each parameter is determined by inspecting the cumulative fraction of total variance explained by the significant harmonics. Results revealed that the number of significant harmonics assigned for the parameters is slightly higher in region with monsoonal rains. The overall simulation results showed that the proposed model is capable of generating tropical rainfall series from convective and monsoonal activities.

    ABSTRACT: Curbing water scarcity problem in semi-arid regions is a top priority for economic and social development. Sustainable domestic water supply alternative strategies are therefore required to augment water supply with affordable cost and technology. Scanty research findings in Sub-Saharan Africa; however, reported inefficiency to adapt water scarcity problems in the region. Therefore, investigation of domestic rainwater harvesting (RWH) reliability seems important to extract factors affecting the system. We found that rainwater harvesting with the existing traditional RWH systems in Mekelle city were unreliable. Unreliability was attributed to inefficient design, as the systems were installed without considering deterministically the stochastic nature of rainfall, family size, water demand, rooftop area and storage tank size.

    ABSTRACT: This review article discusses the climate, water resources and historical droughts of Africa, drought indices, vulnerability, impact of global warming and landuse to drought-prone regions in West, Southern, and Greater Horn of Africa, which have suffered recurrent severe droughts in the past. Recent studies detected warming and drying trends in Africa since the mid-20th century. Based on the 4th Assessment Report of the Intergovernmental Panel of Climate Change, and that of the 5th Coupled Model Intercomparison Project (CMIP5), both northern and southern Africa are projected to experience drying such as decreasing precipitation, runoff and soil moisture in the 21st Century and could become more vulnerable to impact of droughts. The daily maximum temperature is projected to increase up to 8°C (RCP8.5 of CMIP5), precipitation indices such as total wet day precipitation (PRCPTOT) and heavy precipitation days (R10 mm) could decrease, while warm spell duration (WSDI) and consecutive dry days (CDD) could increase. Uncertainties of the above long-term projections, teleconnections to climate anomalies such as ENSO and Madden Julian Oscillation which could also affect water resources of Africa, and capacity building in terms of physical infrastructure and non-structural solutions, are also discussed. Given traditional climate and hydrologic data observed in Africa are generally limited, satellite data should also be exploited to fill in the data gap for Africa in future.

    ABSTRACT: A semi-distributed hydrological model is developed, calibrated and validated against unregulated river discharge from the Tocantins-Araguaia River Basin, northern Brazil. Climate change impacts are simulated using projections from the 41 Coupled Model Intercomparison Project Phase 5 climate models for the period 2071-2100 under the RCP4.5 scenario. Scenario results are compared to a 1971-2000 baseline. Most climate models suggest declines in mean annual discharge although some predict increases. A large proportion suggest that the dry season experiences large declines in discharge, especially during the transition to the rising water period. Most models (>75%) suggest declines in annual minimum flows. This may have major implications for both current and planned hydropower schemes. There is greater uncertainty in projected changes in wet season and annual maximum discharges. Two techniques are investigated to reduce uncertainty in projections, but neither are able to provide more confidence in the simulated changes in discharge.

    ABSTRACT: The application of artificial neural networks (ANNs) is widely used recently in streamflow forecasting because of it flexible mathematical structure. However, several researchers have indicated that using ANN in streamflow forecasting often produces timing lag between observed and simulated time series. In addition, ANN under or overestimate a number of peak flows. In this paper, we proposed three data-processing techniques to improve ANN prediction and deal with its weaaknesses. Wilson-Hilferty transformation (WH) and two methods of base flow separation (One Parameter Digital Filter OPDF; and Recursive Digital Filter RDF) were coupled with ANN to build three hybrid models: ANN-WH, ANN-OPDF and ANN-RDF. The network behavior was quantitatively evaluated by examining the difference between model output and observed variables. The results show that even following the guidelines of Wilson-Hilferty transformation which reduces significantly the effect of local variations, it was found that the ANN-WH model has shown no significant improvement of peak flow estimation neither of timing error. However, combining baseflow with streamflow and rainfall provides important information to ANN model concerning the flow process operating in the aquifer and the watershed systems. The model produced excellent performance in terms of various statistical indices where timing error was totally eradicated and peak flow estimation significantly improved.

    ABSTRACT: In this paper a Universal Multifractals comparison of the outputs of two types of collocated optical disdrometers installed on the roof of the Ecole des Ponts ParisTech is performed. A Campbell Scientific PWS100 which analyses the light scattered by the hydrometeors and an OTT Parsivel2 which analyses the portion of occluded light are deployed. Both devices provide the binned distribution of drops according to their size and velocity. Various fields are studied across scales: rain rate (R), liquid water content (ρ), polarimetric weather radars quantities such the horizontal reflectivity (Zh) and the specific differential phase (Kdp), and DSD parameters such as the total drop concentration (Nt) and the mass-weighted diameter (Dm). For both devices a good scaling is retrieved on the whole range of available scales (2 h—30 s), except for the DSD parameters for which the scaling only holds down to few minutes. For R, the UM parameters are found equal to 1.5 and 0.2 for respectively  and C1. Results are interpreted with the help of the classical Zh-R and R-Kdp radar relations.

    ABSTRACT: In many arid and semi-arid countries, wastewater irrigation is becoming a common practice in agriculture. In this study, the effect of long-term (40 years) wastewater irrigation on selected physical and hydraulic properties of soil in different parts of a landscape was investigated. The performance of some infiltration models, including Philip (Ph), Kostiakov (Kos), Kostiakov-Lewis (Kos-L), Horton (Ho), Huggins and Monke (Hug-M), and linear and nonlinear Smith-Parlange (S-P(L) and S-P(NL)), was compared. This study was done in the Urmia region, Iran, where flooding wastewater irrigation has been practiced for at least 40 years. Five paired sites, each of which contained a measurement location at the wastewater-irrigated (WWI) and adjacent control area were studied. Accuracy of the infiltration models was evaluated using several statistical criteria, including root mean square error (RMSE) and Akaike information criterion (AIC). The models were classified into groups using cluster analysis based on level of similarity in their performance. The cumulative water infiltration into soils after one hour (I1hr) was calculated using the selected most accurate models and introduced so as to use only one term to compare the infiltration behaviour of soils. Based on RMSE and AIC, the performance of the Ph, Ho, Kos and Kos-L models was considerably better than that of Hug-M, S-P(L) and S-P(NL). The ranking of the models in terms of their AIC values was: Kos-L > Ho > Kos > Ph > S-P(L) > Hug-M > S-P(NL). The models were classified in two distinct groups. The similarity among Ph, Ho, Kos and Kos-L models was more than 80% and for Hug-M, S-P(L), and S-P(NL) models, it was more than 79%. However, the similarity between these two groups of models was less than 58%.

    ABSTRACT: Sedimentation in navigable waterways and harbours is of concern for a number of water and port managers. One potential source of variability in sedimentation is the annual sediment load of the river that empties in the harbour. The main objective of this study was to use some of the regularly monitored hydro-meteorological variables to compare estimates of hourly suspended sediment concentration in the Saint John River using a sediment rating curve and a model tree (M5ʹ) with different combinations of predictors. Estimated suspended sediment concentrations were multiplied by measured flows to estimate suspended sediment loads. Best results were obtained using M5ʹ with four predictors, returning an R2 of 0.72 on calibration data and an R2 of 0.46 on validation data. Total load was underestimated by 1.41% for the calibration period and overestimated by 2.38% for the validation period. Overall, the model tree approach is suggested for its relative ease of implementation and constant performance.

    ABSTRACT: Throughout the last decade copula functions were widely used to assess a wide range of hydrological problems, often focusing on two distinct variables. In many of these studies it was ignored whether the two variables of interest actually occurred simultaneously (e.g. two annual maximum time series were analysed in a multivariate statistical framework). Here we introduce a novel approach to derive bivariate design events using copula functions allowing both simultaneous and non-simultaneous occurrence of the variables to be modelled. The methodology is exemplarily applied to assess the combined flood occurrence at the confluence of the Rivers Rhine and Sieg (Germany). The results underline the validity of the methodology. Employing a hydrodynamic numerical model furthermore shows, that commonly used statistical approaches to select a single design event out of a vast number of possible combinations can be critical for practical design purposes.

    ABSTRACT: In recent years there has been a surge in land investments, primarily the African continent but also in Asia and Latin America. This increase in land investment was driven by the food pricing crisis of 2007-2008. Land investors can be identified from a variety of sectors with actors ranging from hedge funds to national companies. Many water scarce countries in the Middle East and North Africa (MENA) are among these financiers, and primarily invest in Africa. Recognizing the potential for “outsourcing” their food security (and thereby also partly their water security) Middle Eastern countries such as Jordan, Qatar and the United Arab Emirates have invested in land for food production in Africa. The extent to which this is happening is still unclear as many contracts are not yet official and the extent of the leases is vague. This paper investigates the land investments and acquisitions by Middle Eastern countries. It also seeks to analyse what effect, if any, these investments can have on the potential for conflict reduction and subsequent peace building in the Middle East region as the activity removes pressure from transboundary water resources.

    ABSTRACT: The Australian Water Balance model (AWBM) and the SimHyd rainfall-runoff model are conceptual models widely used for simulating daily flows in Australia. To evaluate their ability to model non-stationary daily flows, to quantify the effect of land disturbance, and to assess their performance in catchments outside Australia, these two models were applied to two small watersheds, the Fernow watershed No. 6 in West Virginia, USA, for the period 1959-2009, and the River Rimbaud watershed in the French Alps for the period 1968-2006. Both watersheds have experienced well documented disturbances as a result of clearing and fire, respectively. The modelling protocol followed was adopted for a workshop on hydrology under change, held during the 2013 IAHS Assembly in Göteborg, Sweden, which was based on split-sample tests. On balance, the AWBM worked marginally better than SimHyd for these two catchments, and neither model worked satisfactorily for the Fernow watershed where forest clearing, application of herbicide and changes in species composition had occurred. There is little difference in terms of model performance between periods when land disturbances occurred and other periods with relatively stable conditions. Conceptual models are better equipped to simulate climate-driven variations in the observed streamflow (e.g. the River Rimbaud), and inadequate in reproducing streamflow variability as a result of complex forest management practices.

    ABSTRACT: Throughfall drop size distributions (DSDs) are important for plant-soil interactions. This is the first known study to quantify differences in throughfall DSDs with the presence and absence of foliage. Employing a disdrometer, three parameters solely representing throughfall drip were measured and calculated: maximum drop diameter (DMAX), median volume diameter of drops (D50DR), and relative volume percentage of drops (pDR). Beneath Liriodendron tulipifera L. in Maryland (USA), DMAX, D50DR, and pDR were substantially larger when the canopy was unfoliated. In fact, the presence or absence of foliage was one of the primary factors affecting all three throughfall DSDs along with air temperature, according to the boosted regression tree analysis. Experimental results were attributed to differing physical properties of intercepted water between foliated and unfoliated periods and differential water behavior on leaves and bark. Future work should examine the effects of concentrated drip points on the development of throughfall-induced hot spots.
