“…The fluvial events usually occur for the duration of days or even weeks with widespread damages in the floodplains of the river system. On the other hand, pluvial flooding hardly ever happens for more than one day duration with an influence on local regions (Chen et al, 2010;Patra et al, 2016;Apel et al, 2016).…”

Abstract. Flood and flash floods are complex events, depending on weather dynamics, basin physiographical characteristics, land use cover and water management. For this reason, prediction of such events usually deals with very accurate model tuning and validation, which is usually site-specific and based on climatological data, such as discharge time series or flood databases. In this work, we developed and tested two hydrological stress indices for flood detection in the Central Italy Apennine District: a heterogeneous geographical area, characterized by complex topography and medium-to-small catchment extension. Proposed indices are threshold-based and developed taking into account operational requirements of civil protection end-users. They are calibrated and tested through the application of signal theory, in order to overcome data scarcity over ungauged areas, as well as incomplete discharge time series. The validation has been carried out on a case study basis, through the use of flood reports from various source of information, as well as hydrometric level time series, which represent the actual hydrological quantity monitored by civil protection operators. Obtained results shows as the overall accuracy of flood prediction is greater than 0.8, with false alarm rates below 0.5 and probability of detection ranging from 0.51 to 0.80. A slight anticipation of peak occurrence was found, however, the time shift of indices signal peak it is strongly dependent on the presence of dams that regulates the flood propagation. Moreover, the different nature of the proposed indices suggests their application in a complementary way, as the index based on drained precipitation appears to be more sensible to rapid flood propagation in small tributaries, while the discharge-based index is particularly responsive to main channel dynamics.

“…However, urban floods may have different sources and are called riverine flood, when the main river bed exceeds its capacity; stormwater flood, when the conveyance capacity of the urban drainage system is exceeded; or coastal flood, when the seawater causes the flooding. Only stormwater floods may affect any city, even if neither is a coastal city nor have a nearby river to be overflowed (Patra, Kumar, & Mani, ; Kundzewicz et al, ).…”

Before the solid waste is dumped in landfills, the collection process for large Spanish cities starts from a regular collection of household waste municipal service which is carried out through street containers. When an urban flood occurs those containers may lose their stability, thereby allowing debris (i.e., solid waste contained) and leachate to escape from the container and contaminate the flood water.

Taşkın, son yıllarda iklim değişikliği ve şehirleşmenin de etkisiyle sayısız zararlara yol açan bir doğal afettir. Taşkının zamanını, büyüklüğünü ve şiddetini bilmek; taşkının olumsuz etkilerini azaltmak için son derece önemlidir. Taşkının hidrolik modellemesinin yapılarak etki alanı tahmin edilebilir. Bunun için de maksimum taşkın debisini bilmek gerekir. İstatistik, sentetik ve hidrolojik model yöntemleri ile hesaplanan taşkın debisinin oluşturduğu taşkın hidrografı, hidrolik modele altlık olur ve taşkın risk haritaları belirlenebilir. Bu çalışmada Mockus, Snyder, Rasyonel ve DSİ sentetik yöntemleri ile taşkın frekans analizi ve ayrıca MIKE hidrolojik model programı yardımıyla taşkın pik debileri, 21.682,8 km 2 alana sahip Doğu Akdeniz Havzası için hesaplanmıştır. Sonuç olarak geniş bir havzada çok sayıda gözlem istasyonu yardımıyla havza büyüklüğüne göre en uygun taşkın debisi tahmin yöntemleri belirlenmiştir.
