Vertical Circulation in Density-Stratified Reservoir
The paper presents a mathematical model of vertical circulation in density-stratified reservoirs. An analytical solution of the formation of circulation regions is presented. The solutions...

Recovery in Large Diameter Wells
A closed-form approximate analytical solution for recovery in fully penetrating large diameter wells tapping a confined aquifer is presented. The solutions are also applicable for unconfined...

Point Slope Approach for Reservoir Flood Routing
The point-slope method of routing floods through reservoirs uses equations and criteria for determining the outflow hydrograph slope and the inflection point of the rising limb of the...

Worth of Inflow Forecast for Reservoir Operation
This study assesses improved benefits that might be gained from the use of long-range streamflow forecasts in the operation of a typical multipurpose reservoir. Long-range is defined as...

Planning Considerations for Detention Basins

Long-Term Salinity Calculation in Delaware Estuary
A mathematical model of time-varying salinity distribution is selected and further developed for the purpose of calculating over a period of time equal to a year or more. These calculations...

Furrow Advance Rates under Surge Flow Systems
Two field tests were conducted to study the effect of cycling furrow inflows on advance rates. Earlier investigations had demonstrated the concept and termed it surge flow irrigation based...

Optimal Design of Border Irrigation Systems
Using a surface irrigation hydraulics simulation model, relationships were developed between water requirement efficiency and the system design variables. A crop production function was...

Wetlands' Use for Water Management in Florida
The 2,300 square mile (6,000 km²) Kissimmee River Basin in Central Florida is under pressure for rapid expansion due to urban encroachment and agricultural activities. The river contributes...

Pesticide Transport and Bioconcentration Model
A pesticide transport and bioconcentration model has been developed and applied to Coralville Reservoir, Iowa, for the insecticide dieldrin. Two spatial configurations, a two compartment...

Predicted Limnology of a Proposed Reservoir in Southwest Colorado

Optimum Spillway Breadth for Gravity Dams
The provision of overflow capacity in an impounding reservoir may occupy a large fraction of the total project cost. With a higher cost per unit volume than elsewhere in the dam, an optimum...

Mathematical Model of Border Irrigation
The model can predict the rates of advance and recession and the duration and depth of infiltration at any point in a border when slope, length, roughness, inflow rate and infiltration...

Design of a Test to Study Salinity Response in a Major Estuarine System to Major Storm Inflow

The Issue of Freshwater Inflow to Estuaries

Simplified Muskingum Routing Equation
The Muskingum method and its variations are well established in the flood routing literature. Traditionally, its parameters K and X...

Dimensionless Advance for Level-Basin Irrigation
Graphical solutions in dimensionless form are presented for the advance of an irrigation stream in a level basin. The solutions are based on the equations of continuity and momentum under...

Inlet Stability Solutions for Tributary Inflow
Formulas in use relating to the flow of water through tidal inlets do not take into account the joint effects of inertia and tributary inflow that play a significant role in determining...
