For early warning of disasters induced by precipitation (such as floods and landslides), different kinds of rainfall thresholds are adopted, which vary from each other, on the basis on adopted hypotheses. In some cases, they represent the occurrence probability of an event (landslide or flood), in other cases the exceedance probability of a critical value for an assigned indicator I (a function...

A simplified, vertically-averaged model of soil moisture interpreted at the daily time scale and forced by a stochastic process of instantaneous rainfall events is compared with a vertically-averaged model which uses a nonoverlapping rectangular pulse rainfall model and a more physically based description of infiltration. The models are compared with respect to the importance of short time-scal...

Abstract. Ephemeral streams are highly dependent on rainfall and terrain characteristics and, therefore, very sensitive to minor changes in these environments. The western Mediterranean area exhibits a irregular precipitation regime with great variety of events driving the flow generation intermittent watercourses, future climate change scenarios depict lower magnitude higher intensity this are...

Methodologies for rainfall-runoff event identification from continuous time series suffer significant subjectivity. In particular, whether they initiate the rainfall or streamflow timeseries, usually require baseflow separation and need substantial modifications parameters’ recalibration when changing temporal resolution of data. Therefore, here we propose a novel objective methodology that is ...

An attempt has been made in the present research to simulate a deadly flash-flood event over City of Skopje, Macedonia on 6 August 2016. A cloud model ensemble forecast method is developed super-cell storm's initiation and evolutionary features. Sounding data are generated using an approach, that utilizes triple-nested WRF model. three-dimensional (3-D) convective (CCM) with very fine horizonta...
