(199007)This comparative biogeochemical analysis focused on the patterns and processes of aluminum cycling in two small watersheds, one in the west‐central Adirondacks of New York and the other on Cumberland Plateau of eastern ...

(197102)A set of monthly streamflow records is generated and analyzed to give a set of synthetic critical periods. Some characteristics of these periods are derived, and the mean and standard deviation of their values are compared ...

(197102)A radiation balance method and a modified radiation balance method were used to determine hourly and daily values of atmospheric thermal radiation on three clear and three cloudy days during February and March 1970 at ...

(199306)An estimate of barometric efficiency, often necessary for aquifer pump test interpretation, is difficult to obtain when there is a trend in water levels over time. Ordinary least squares (OLS) regression methods can be ...

(197612)The U.S. Department of Agriculture Hydrograph Laboratory model of watershed hydrology is adapted for use on a research watershed where land use changed drastically as a result of reforestation and subsequent thinning. Eight ...

(198502)This paper reports a set of model performance calculations for three event‐based rainfall‐runoff models on three data sets involving 269 events from small upland catchments. The models include a regression model, a unit ...

(199304)Time‐stratified sampling of sediment for estimating suspended load is introduced and compared to selection at list time (SALT) sampling. Both methods provide unbiased estimates of load and variance. The magnitude of the ...

(199203)Several well‐known evaporation equations were tested with daily data averaged over six stations in a 15×15 km region in Kansas. The equilibrium evaporation and advection‐aridity evaporation equations produced acceptable ...

(198605)Two geostatistical approaches for the estimation of hydraulic conductivity and hydraulic head from hydraulic conductivity and hydraulic head measurements are developed for two‐dimensional steady flow with sinks. For both ...

(198510)Computational efficiency and computer memory requirements for four methods of minimizing functions were compared for four test nonlinear‐regression steady state groundwater flow problems. The fastest methods were the ...

(198710)The amount and distribution of liquid water are important for assessing the mechanical strength, meltwater generation, and meltwater transmission in snow. Liquid water also has a profound effect on the performance of active ...

(197612)A recent solution obtained by Babu when the soil water diffusivity has an exponential behavior is compared with two earlier solutions. It is shown that with a slight modification, Babu's perturbation solution is identical ...

(198108)This paper compares the efficiency of the strongly implicit procedure (SIP) and the incomplete Cholesky‐conjugate gradient method (ICCG) applied to the solution of the finite difference approximating equations for groundwater ...

(197808)Measurements of long‐wave radiation at Sidney, Montana, indicated that both an analytically derived equation and an empirically derived equation for clear‐sky conditions adequately predict the long‐wave radiation flux at ...

(198909)A composite analytical model is developed for analyzing the results of pumping tests where the influence of well bore storage and a skin region of finite thickness are present at the pumping well. The solution of the ...

(199306)This paper proposes a composite L1 parameter estimator to solve the inverse problems in groundwater flow and solute transport modeling. The estimator is formulated using a weighted L1 norm as the error measure between the ...

(199612)A pore‐scale lattice model for fluid displacement in porous media is used to investigate the effect of temperature on (1) soil drainage and (2) soil freezing. The model is calibrated for a given soil, that is, input ...

(198304)There is an increasing concern regarding the contamination of groundwater by hazardous materials. This concern is now being translated into private and public sector initiatives to implement waste disposal and other policies ...

(198411)When net recharge is less than about 0.03 mm/yr, moisture movement in deep unsaturated zones at steady state will be dominated by upward movement of vapor driven by the geothermal gradient. With zero net recharge there ...

(197406)A conceptual model of the capillary hysteresis phenomenon is suggested. The advantage of this model is that all scanning curves are derived with the aid of simple functions from the main drying curve and the main wetting ...
