Density Currents
access_time 2021-09-06T11:16:36.54Z face online5
Density Currents DENSITY CURRENTS The water stored in the reservoir is generally free from silt. The flood inflow is generally muddy and heavily charged with silt. Thus during floods there are two waters having different densities present is the reservoir. Heavily silt charged water flows along the...
Reservoir sedimentation

Reservoir sedimentation RESERVOIR SEDIMENTATION All the waters entering the reservoir carry some amount of silt. The amount of silt in the water coming into the reservoir depends upon the topography, nature of the soil, vegetation cover over the catchment, and also upon the intensity of rainfall. I...
Reservoir losses

Reservoir losses RESERVOIR LOSSES Reservoir losses may be classified under following three heads. Evaporation losses Absorption losses Reservoir leakage or percolation losses.1. Evaporation Losses. These are the major losses from a reservoir. This loss is affected by expos surface area of the reser...
Flood Control
access_time 2021-09-06T10:52:53.913Z face online5
Flood Control FLOOD CONTROL Flood is a relatively high flow. The floods cause overtopping of natural as well as artificial banks of the streams. The flood is caused by run off from rainfall and/ or melting snow, too large to be confined in the banks of streams. When banks are overtopped the flood w...
Measurement of velocity of flow
access_time 2021-09-06T10:47:17.46Z face online5
Measurement of velocity of flow MEASUREMENT OF VELOCITY OF FLOW Before we actually discuss various methods to measure the velocity of flow, it is worthwhile to explain the variation in the velocity along the cross-section of the river. The velocity of flow is not uniform throughout the cross-sectio...
