Explicit Aquifer Diffusivity Estimation Using Linearly Varying Stream Stage
Publisher: American Society of Civil Engineers
Abstract: For a stream fully penetrating an unconfined aquifer, different approaches are available to estimate aquifer diffusivity. However, these approaches involve an interpolation of tabulated values or type-curve matching. Certain ...
Outlet Scour Modeling for Drop Height Influence
Publisher: American Society of Civil Engineers
Abstract: Modeling of scour below pipe outlets has received considerable attention in the literature. However, there has been disagreement regarding the inclusion of the effect of drop height in the modeling procedure. For the purpose ...
Analysis of Flow through Lateral Slot
Publisher: American Society of Civil Engineers
Abstract: Analysis of diversion of flow has received considerable importance in existing literature. In this study, diversion of flow through a lateral slot is analyzed using the spatially varied flow equation and the elementary ...
Pump Test Analysis of Confined Aquifer
Publisher: American Society of Civil Engineers
Abstract: The storage coefficient and transmissivity are important aquifer parameters that are useful in assessing the ground‐water potential of an aquifer. For a nonleaky confined aquifer, these parameters can be determined with ...
Pumping-Test Analysis of Wells Having Storage Contribution
Publisher: American Society of Civil Engineers
Abstract: In general, pumping tests are performed in borewells as well as in dug wells. Depending on the radius of the pumping well, the storage effects influence the aquifer parameter estimation. To account for the storage effects, ...
Nonlinear Root-Water Uptake Model
Publisher: American Society of Civil Engineers
Abstract: Sound irrigation management requires information about root-water uptake patterns of different crops. In the existing literature, the extraction rate of soil moisture by the roots is assumed to be either constant or varying ...
Ground-Water Mound Equation for Rectangular Recharge Area
Publisher: American Society of Civil Engineers
Abstract: Artificial recharge of the ground-water table from rectangular basins has been the subject of extensive study in the last 30 years. Although, for finite aquifers, the ground-water mound profile can be accurately predicted, ...
Modeling of Free Surface in Steady-State Radial Seepage
Publisher: American Society of Civil Engineers
Abstract: The free surface occurs as one of the boundaries in all unconfined ground-water flow problems. Determination of the free surface has received considerable attention in the literature. For computing free surface, models ...
Bed‐Load and Suspended‐Load Transport of Nonuniform Sediments
Publisher: American Society of Civil Engineers
Abstract: Methods are available for the computation of the bed‐load and suspended‐load transport rates of uniform sediments. However, limited studies exist for nonuniform sediments. These studies, in general, lack simplicity, and ...
