The World Small Hydropower Development Report (WSHPDR) 2022 is the result of an enormous collaborative effort between the United Nations Industrial Development Organization, the International Center on Small Hydro Power and over 200 local and regional small hydropower (SHP) experts, organizations, engineers, academics and government officials from...

One of the UN agenda 2030 Sustainable Development goals is associated with water availability and its sustainable management. The present study intends to improve multipurpose reservoir management under climate change scenarios in water scarce regions such as the Mediterranean. Implemented methods include the sequential use of climate model results...

Water quality modeling can be an important tool for lake management. However, if the simulation period is small and the forcing data is limited, the result uncertainty may diminish its usefulness. This study was conceived with the aim of implementing a long-term water quality simulation of a shallow eutrophic lagoon, with limited forcing data, to e...

The complexity of the state-of-the-art climate models requires high computational resources and imposes rather simplified parameterization of inland waters. The effect of lakes and reservoirs on the local and regional climate is commonly parameterized in regional or global climate modeling as a function of surface water temperature estimated by atm...

Livro sobre a água e os rios no futuro em Portugal. A publicação integra um conjunto de contributos temáticos de vogais do Conselho Nacional da Água, bem como um capítulo final de discussão. Espera-se que o conteúdo deste documento possa ser útil nos próximos ciclos de planeamento de recursos hídricos e nas decisões políticas de fundo que forem tom...

The main objective of INNOMED is to develop alternative management options in forestry and agriculture, improving water use efficiency, promoting sustainable land use and water management solutions at the river basin level. Reservoirs in the Degebe river basin (Alentejo region): Monte Novo, Vigia and Esporão, providing water to agriculture (3000 ha...

Changes in water temperature and stratification dynamics can have a significant effect on hydrodynamics and water quality in reservoirs. Therefore, to assess future climate impacts, projections of three regional climate models for Europe, under the IPCC A1B emission scenario (2018–2100), were used with the CE-QUAL-W2 water quality model to evaluate...

The Alqueva dam, constructed in the Portuguese section of the Guadiana River, is the centre of a multipurpose project under development in Alentejo, Portugal, which includes strategic water storage, hydropower production, irrigation and urban water supply. Aiming to adequately evaluate nutrient control strategies along the Alqueva watershed in Port...

The need for a better management of estuaries requires an environmental characterization following a methodology that allows the comparison of distinct estuarine systems and the assessment of their evolution. The peculiar characteristics of estuaries, in particular their intrinsic variability, make this characterization difficult and there is no co...

RESUMO Por razões relacionadas com a sua génese, as ilhas vulcânicas do Açores são, na sua generalidade, parcelas de pequena dimensão e com forte desenvolvimento em altitude pelo que a variação espacial das condições climáticas é mais acentuada e mais rápida do que em outras regiões mais aplanadas. De uma forma bem evidente verificam-se fortes incr...

The aim of this document is to present and discuss the results of the experimental work undertaken in Laje stream, in a section near the village of Oeiras in Portugal. The work was developed with the main objective of characterising stormwater quality in Portuguese drainage systems, and to predict the effects of the performance of partially separat...

O estudo e compreensão dos fenómenos que provocam uma cheia é fundamental para a segurança das populações e dos bens que se encontram em zonas ciclicamente inundáveis. Estes locais são preferenciais para a fixação de população, tanto pela via de comunicação fluvial, como pela fertilidade dos solos aluvionares. O aspecto mais relevante desta comunic...

Este artigo apresenta um modelo de precipitação/escoamento superficial que toma em consideração o fenómeno distribuído em toda a área da bacia. A metodologia é válida para todos os pontos da bacia, encosta ou linha de água, pelo que o modelo apresentado é uma ferramenta de análise adequada para a previsão das modificações induzidas na relação preci...

The recent developments in multimedia and virtual reality technologies allow water resources to be studied with the realism associated with site investigations and the "What if" analysis capabilities common in simulation systems. The proposed virtual reality water quality management systems relies upon the realistic representation of a watershed in...

In Portugal reservoirs play an important role in the regulation of the availability of water because rivers have a highly variable flow regimen during the year. Due to the multiple and often conflicting uses of reservoirs it is essential to be able to forecast their evolution with respect to present and proposed uses. The characterization of reserv...

A decision support system for the water-quality management of the Tejo estuary, named Hypeitejo, is presented. Hypertejo is based on a chain of data bases, dispersion, nonpoint pollution, and regional water-quality management models. Due to large running times of some of the models, making their interactive use impossible, Hypertejo was designed as...

Estuarine dispersion models have been commonly used to define the pollutant loads permissible to achieve pre-defined water quality levels and improve our knowledge of estuarine phenomena. Those models for large estuaries with complex hydrodynamic and ecological processes usually have extremely high running times. This paper presents an approach bas...

Resumo Foi aprovado pelo Governo Português em 2007 o Programa Nacional de Barragens com Elevado Potencial Hidroeléctrico (PNBEPH). O Programa foi sujeito a um trabalho de avaliação ambiental estratégica (AAE), sem precedentes neste tipo de programa. A AAE do PNBEPH tem o mérito de desenvolver uma análise de âmbito nacional de um conjunto de barrage...

In order to determine the effects of thermal discharges from an existing power plant on the water quality of a nearby river with tidal effect, CE-Qual-W2 model was applied. This study aimed the evaluation of the impact on river water temperature after an increase of discharged volumes, due to planned reinforcement of power production. Due to the re...

Describes design aspects of a large river training project in Portugal. Works were carried out in the lower, flat area of the Mondego River basin. Two types of structures and the particular problems associated with their design are focused upon: confluences and tributaries, and transversal groynes and blocks for energy dissipation. Main design requ...

Discusses design aspects of lateral discharge control works in trained rivers with longitudinal dikes. Their location associated to plain compartmentation, and analytical and numerical formulations for estimating water surface profiles along dikes for floods exceeding the design flood are considered. A case study of a recently trained river using a...
