Hydrograph recession constants are required in rainfall-runoff models, base flow augmentation studies, geohydrologic investigations and in regional low-flow studies. The recession portion of a streamflow hydrograph is shown to be either an autoregressive process or an integrated moving average process, depending upon the structure of the assumed model errors. Six different estimators of the bas...

This study uses the 1989 Canada-U.S. Free Trade Agreement as a source of exogenous shock to product markets to establish a causal effect of competition on acquisition returns to shareholders. Following the agreement, acquirers exposed to greater increases in competitive pressure experience higher announcement returns. The positive impact of increased competition is stronger in acquirers with re...

The most widely and popularly used method for prediction of flood hydrograph resulting from a known storm in a basin area use historical rainfallrunoff data and unit hydrographs derived from them. These procedures are highly unreliable due to the climatic and physical changes in the watershed and their implementation to ungauged catchments. The use of physically based rainfall-runoff estimation...

We examine how firms redraw their boundaries after acquisitions using plant-level data. We find that there is extensive restructuring in a short period following mergers and full-firm acquisitions. Acquirers of full firms sell 27% and close 19% of the plants of target firms within three years of the acquisition. Acquirers with skill in running their peripheral divisions tend to retain more acqu...

Abstract Floods occur due to several factors including topographic conditions, high rainfall intensity, blockage of water flow, lack infiltration areas, deforestation, and so on. The Tojo watershed is included in the Parigi-Poso river area, with an area 211,830 km2 a length 25.52 km. In watershed, it necessary study flooding, because always flows every year. This research aims find out how much...
