Integrated Water Resource Management

As defined by the Global Water Partnership, integrated water resource management is a process which promotes the coordinated development and management of water, land, and related resources in order to maximize the resultant economic and social welfare in an equitable manner without compromising the sustainability of vital ecosystems. Resources available within this theme provide guidance on how to conserve and restore watersheds, reduce pollution, adapt to climate change and reduce risks from floods and droughts.

Economics of Hydrologic Modelling

Published: 
May 1, 1972
U.S. Agency for International Development
The proliferation of hydrologic models suggests either a situation where-in hydrologists are homing onto the true model or a situation wherein hydrologists are uncertain about the appropriate model. The latter seems more likely in the face of constraints on data availability, budgets, time,...Read more

Studies of the Biogeochemistry of Boron: Concentrations in Surface Waters, Rainfall, and Aquatic Plants

Published: 
April 12, 1972
U.S. Agency for International Development
Boron concentrations in streams, swamps, ponds and reservoirs of the southeastern United States were usually below 100 ppb. Levels of boron in rainfall varied greatly between different periods of precipitation, but the highest concentrations were observed during winter. However, most rainfall...Read more

Salt Water Coning Beneath Fresh Water Wells

Published: 
April 1, 1972
U.S. Agency for International DevelopmentColorado State University
This research investigates the phenomenon of salt water coning below a discharge well partially penetrating an aquifer in which fresh water is underlain by saline water. The first portion of this report is concerned with the evaluation of techniques presently available for analyzing the performance...Read more

Development Institutions, Projects, and Aid in the Water Development Program of East Pakistan

Published: 
March 1, 1972
U.S. Agency for International Development
Water is a critical factor in East Pakistan's economy. Of the total surface area, 6% is river. The rural inhabitants (90% of populations) are subject to flood and drought. During drought months agriculture is only possible if water can be obtained from the rivers or groundwater for irrigation.Read more

Installation and Field Use of Cutthroat Flumes for Water Measurement

Published: 
March 1, 1972
U.S. Agency for International DevelopmentColorado State University
The cutthroat flume has been developed for operation under both free flow and submerged flow conditions. The flume has a flat bottom and vertical walls. Its most obvious advantage is economy, since fabrication is facilitated by the flat bottom and removal of the throat section. Also, any particular...Read more

Cutthroat Flume Discharge Relations

Published: 
March 1, 1972
U.S. Agency for International DevelopmentColorado State University
The purpose of this study is to rate a group of cutthroat flumes which have the same geometric shape. Because of geometric similarity, the behavior of all flumes which are dimensionally similar to those tested should be capable of being predicted within a degree of accuracy suited for field use...Read more

Culverts as Flow Measuring Devices

Published: 
February 1, 1972
U.S. Agency for International DevelopmentColorado State University
Culverts are encountered throughout irrigation systems. Many of these culverts operate under free surface flow conditions. Usually, the flow depths in the culvert are governed by downstream flow conditions. This particular flow condition can be described as free surface outlet control. Only an...Read more

Estimation of Irrigation Requirement for Venezuela

Published: 
January 1, 1972
U.S. Agency for International Development
Christiansen's formula was used to compute evaporation and potential evapotranspiration using 1013 months of data from 19 stations in Venezuela. Thirteen probability levels of precipitation were determined for each station. Potential irrigation requirements for 16 stations were computed based...Read more

The Indus Rivers and Tarbel Dam

Published: 
January 1, 1972
U.S. Agency for International Development
A FAIRLY BRIEF HISTORY OF THE INDUS RIVER BASIN, WITH SPECIAL EMPHASIS ON THE HISTORY OF THE TARBELA DAM. THE REPORT BEGINS WITH A QUICK DESCRIPTION OF THE INDUS RIVER BASIN AND THEN DISCUSSES THE INDEPENDENCE OF INDIA AND THE CREATION OF PAKISTAN. WITH PARTITION CAME CONFLICT OVER THE RIVER AND IN...Read more

Analysis and Application of a Digitally Simulated Electronic Watershed Analog

Published: 
January 1, 1972
U.S. Agency for International Development
Watershed modelers are faced with two conflicting requirements in selecting a model for the simulation of watershed hydrologic processes. The first is to select a model that is as descriptive as possible and second is to avoid over-complexity. The electric watershed analog described in this report...Read more
