Purpose of study was to quantify canal water distribution and its impact on income of the farmers in selected watercourse of 3-R distributary before and after the remodeling of outlets. The study was conducted on 3-R distributary of subsystem 6 in district Bahwalnagar of Punjab, Pakistan. Total 9 watercourses were selected of subsystem 6 of 3-R distributary. The subsystem 6 was divided into 3 reaches i.e. the Head, Middle and Tail reaches, and three watercourses were selected in every reach of field study. For every watercourse, Farmers interview at head, middle and tail ends was ...

Nara Canal is a perennial irrigation canal
having six falls but two falls on the canal at RD 26 and RD
139 are found to be favourable for hydropower development.
A number of layouts plan has been studied by collecting
discharge data for the years 1995 to 2005 and flow duration
curves were prepared to ascertain the availability of
flows. For design discharge of the studied layouts, flow of
311 m3/s and 307 m3/s for Layout-A and Layout-B
respectively which were available 30% time of the year...

Knowledge of flow resistance for different
flow conditions helps for better understanding of water
resources problems, such as flood routing, channel
enhancement, backwater curve computation, and scouring.In
studies of flow with suspended sediment two issues often
raised are the effect of suspended sediment on velocity
distribution and flow resistance. The material going into
suspension changes the flow and fluid characteristics and,
as such, influence on the resistance to flow. So it is
...

Floodplain is an area adjacent to the main
river channel and is very fertile to agriculture;
therefore, these areas have been widely developed for
agriculture and settlement purposes. As a result, floods
have caused enormous damages to life, property and
agriculture many times in the past. The river Indus doesnt
flow in a single main channel. At some places it is divided
into two channels and water flows even in the low flow
season. Consequently, the areas in between these channels
...

Steep flowing surfaces like spillways, sluicing outlets and bottom outlets are important hydraulic structures for safety of a dam. Due to high velocities combined with low pressure cavitation may occur on the bottom surface of the chute causing major damage or even endanger the dam stability. This study was carried out to analyze the Diamer Basha Dam spillway for cavitational risk. Data was taken from the report of the model study (Basha Diamer Dam project hydraulic model studies sectional model of spillway Technical Report June, 2005)and the estimated values of flow velocity, cavitaion index...
