Existen múltiples proyectos de restauración de arroyos y ríos, los cuales difícilmente son sujetos a un proceso sistemático de evaluación (Kondolf, 1995). Esto mismo puede aplicarse a las acciones de conservación de suelo y agua en México. Este trabajo buscó evaluar y recuperar las lecciones aprendidas así como el impacto y los indicadores de éxito...

A Mexican National Standard, under a workgroup study defined by National Water Commission, is being proposed based on analyzing and integrating a variety of nationals and internationals experiences, related to the establishment of Environmental Flows (EF). The basin is partitioned to be studied in suitable hydrological subsystems, and then the stud...

(See English below) Este capítulo ofrece una evaluación ecorregional basada en cuencas hidrográficas relacionadas con la hidrología, las políticas de gestión del agua y la biodiversidad de la cuenca del Rio Bravo y Conchos. Brinda además la declaratoria conjunta México- EUA para Rio Grande-Bravo. // This chapter offers an eco-regional assessment ba...

In Mexico, due to reduced and unevenly distributed hydrological resources and incipient water management capabilities, climate change adaptation in the water sector is recognized as an urgent issue. To derive lessons for climate change adaptation, this paper evaluates the results gained after five years of an integrated river basin management (IRBM...

As part of a scientific research project about alpha radioactivity in groundwater for human consumption at the Chihuahua City, the charac- terization of rock sources of radioactivity around de Chihuahua valley was developed. The radioactivity of groundwater and sediments was determined, too. The radioactivity of uranium- and thorium- series isotope...

The Chihuahua-Sacramento valley is an area of 6 km wide by about 32 km in length, it is located from north to south. In the area, at least two zones exist that may have rocks with radioactive minerals: The Pastorías zone at the SW and the Majalca-San Marcos zone to the NW. The latter, was the object of the present investigation. By studying the geo...

The watershed of the Conchos River is the main watershed of the state of Chihuahua, Mexico, and it is the main source of water of the watershed of the Grande river downstream El Paso, Texas. Such part of the watershed of the Grande River is also the border between Mexico and the United States of America, from El Paso-Ciudad Juarez up to Brownsville...

The activity concentration of 222Rn, 226Ra and total uranium in groundwater samples collected from wells distributed throughout the state of Chihuahua has been measured. The values obtained of total uranium activity concentration in groundwater throughout the state run from <0.03 up to 1.34 Bq l-1. Generally, radium activity concentration was <0.16...

The U.S. Department of Energy sponsored the drilling of three wells in 2003 near the Nopal I uranium deposit at the Sierra Pena Blanca, Chihuahua, Mexico. Piezometric information is being collected to understand groundwater flow at local and regional levels as part of an ongoing natural analogue study of radionuclide migration. Water level monitori...

This doctoral dissertation is an investigation of the underground water resources of a typical urban center in and northern Mexico, the City of Chihuahua. In the first part of the investigation I analyzed by remote sensing the urban growth and the consequent water demand and supply of the city of Chihuahua over a period of 22 years (1975-1997). A l...

The City of Chihuahua is located in the central portion of the state of Chihuahua in northwestern Mexico. The water resources in this semi-arid region are scarce and the city is experiencing difficulty meeting its water needs. Most of its water comes from nearby basins whose structure is poorly known, other than the recognition that the area is loc...
