We present a procedure that uses nonlinear optimization theory to plan complex, three-dimensional well paths and path corrections while drilling. The problem of hitting a 3-D target is posed as seeking a profile that optimizes some well-defined objec

The Muskingum method of flood routing is revisited. A survey of literature indicates that the initial condition proposed by Gill is incompatible with the Muskingum hypothesis, that the translatory characteristics later derived by Gill are based on un

The coefficients in the General Hydrologic System (GHS) model of Chow and Kulandaiswamy (1971) are estimated using the method of cumulants. Based on this method a rational criterion is developed to determine the number of terms to be retained in the

Given two linear control systems with reachable sets $R_1 (t)$, $R_2 (t)$, respectively, and a constant matrix M, directly verifiable necessary and sufficient conditions are obtained for the coincidence $R_1 (t) = MR_2 (t)$ for all $t > 0$.

The Chow-Kulandaiswamy general hydrologic system (GHS) model is revisited. Based on a mathematical study by Singh and McCann the GHS model is simplified. Explicit solutions are obtained for special cases which can satisfactorily determine watershed s

The general Hydrologic System (GHS) model is considered. It is found that there are inconsistencies in equations for the instantaneous unit hydrograph (IUH) which were derived using the GHS Model. The existence of these inconsistencies is supported b

We show that if a flow (R, X, π) on a separable metric space (X, d) satisfies (i) the transition mapping π(t, •): X → X is non-expansive for every t ≥ 0; (ii) X contains a globally uniformly asymptotically stable compact invariant subset, the

The Meixner functions are utilized to relate the effective rainfall, the direct runoff and the unit hydrograph through linkage equations. The linkage equations are then employed to derive the unit hydrograph for given rainfall-runoff data on a small
