Towards a generic conceptual model for the propagation of drought through the terrestrial part of the hydrologic cycle.

Drought is a sustained and regionally extensive occurrence of below average natural water availability due to low precipitation, high evaporation rates, and/or high temperature. It can thus be characterised as a prolonged deviation from normal conditions of the natural system (climate and hydrology), which is reflected in variables such as precipitation (meteorological drought), soil moisture (agricultural drought), groundwater and streamflow (hydrological drought). Drought occurs in all climate regions, although the development and effects can be different. Drought should not be confused with aridity, which is a long-term average feature of a dry climate, or with water scarcity, which reflects conditions with long-term imbalances of available water resources and demands (e.g. Tallaksen and Van Lanen, 2004)

Menuju model konseptual yang umum untuk penyebaran kekeringan melalui bagian terrestrial dari siklus hidrologi

Kekeringan adalah ketersediaan air alami di bawah rata-rata yang berkelanjutan dan terjadi di regional tertentu yang terjadi secata ekstensif karena rendahnya curah hujan, tingkat penguapan yang tinggi, dan / atau suhu yang tinggi. Hal demikian dapat dicirikan sebagai deviasi yang berkepanjangan dari kondisi normal dari sistem alam (iklim dan hidrologi), yang tercermin dalam variabel seperti curah hujan (meteorological drought), kelembaban tanah (agricultural drought), air tanah dan streamflow (hydrological drought). Kekeringan terjadi di semua daerah iklim, meskipun perkembangan dan efeknya dapat berbeda-beda. Kekeringan tidak boleh disamakan dengan kegersangan, yang disebakan oleh ikrim kering yang rata-rata berjangka panjang, atau dengan kelangkaan air, yang mencerminkan kondisi ketidakseimbangan jangka panjang antara ketersediaan dan permintaan sumber daya air ( Tallaksen dan Van Lanen, 2004)
