This paper aims to develop a computational model assess and evaluate the annual water level fluctuation (WLF) impacts their trends along any open channel (river, canal or lake) provide reliable information that may help handle implications. The are related recession, flood plain areas, uncovered river bars islands, locations of navigation bottle necks, dredging works. is developed using Excel S...

We investigate the spectral fluctuation properties of constrained ensembles of random matrices (defined by the condition that a number NQ of matrix elements vanish identically; that condition is imposed in unitarily invariant form) in the limit of large matrix dimension. We show that as long as NQ is smaller than a critical value (at which the quadratic level repulsion of the Gaussian unitary e...
