In the proposed model, hydrological processes are defined as all processes of interaction between meteoric water and the physical landscape, such as drainage (both organized and unorganized).

In the proposed model, the spatio-temporal characteristics of the event itself is treated in terms of inflow volumes within a defined area and the response of the physical landscape, is understood as modifications to the landscape itself when it’s subjected to an impulse.

To these, which are main research areas of the "LOCAL HYDROLOGICAL RESPONSE" model, another is added and is represented by the role of climate change in hydrological instability processes.

The first two areas are well-covered on the webpage:

CHARACTERIZATION OF THE HYDROLOGICAL EVENT

The response of the physical landscape to the stimulus produced by a generic, even extreme, weather event is covered on the webpage:

ADAPTATION OF THE PHYSICAL LANDSCAPE

The role that climate change plays in the hydrological responses of the physical landscape to impulses induced by weather events is covered on the webpage:

CLIMATE CHANGE AND LOCAL HYDROLOGICAL RESPONSE

In the discussion of this “Local Hydrological Response” model, we attempt to define, through various direct and indirect means, the range of specific cases that determine the collapse of the hydrological and geomorphological systems.

We attempt to define also the set of geomorphological and meteo-climatic conditions for which the systems are stable so the concept of a HYDROLOGICAL and GEOMORPHOLOGICAL STABILITY FIELD is introduced.

CHARACTERIZATION OF THE HYDROLOGICAL EVENT.

In the proposed model is assumed that the hydrological event is characterized when is well defined into the horizontal plan and also along the altitude or along the vertical direction.

So to characterize an hydrological event will be analyzed the variations of the geographical distribution of inflow volumes within the time frame of the event.

Infact, in the proposed model is assumed that values of precipitation’s height vary more significatively in space and time than related inflows volumes of water.

So, in the proposed model, is assumed that the inflow water’s volumes is a variable much more easy to manage than height of precipitations.

In this context, for any given portion of territory, three phases or processes for characterizing the events that occur there are distinguished:

EVENT RECONSTRUCTION

EVENT MONITORING

PREDICTIVE ANALYSIS

EVENT RECONSTRUCTION

Through event reconstruction, a past event is analyzed and characterized by reconstructing the geographical distribution of inflow volumes within a defined and discretized territory (broken down into smaller units at time intervals suitable for the objectives). This is done to characterize the event, classify it, and archive it for future comparisons with other events, whether ongoing, past, or expected in the near future.

EVENT MONITORING

Event monitoring consists of analyzing and monitoring the variations in the geographical distribution of water inflow volumes in a given, defined, and discretized territory (broken down into smaller units at time intervals suitable for the objectives) as the event itself unfolds. This is done to characterize the event, classify it, and archive it for future comparisons with other events, whether ongoing, past, or expected in the near future.

PREDICTIVE ANALYSIS

Predictive analysis consists of analyzing and characterizing an event expected to occur in the immediate or near future by analyzing the temporal variation of the geographical distribution of water inflow volumes within a given, defined, and discretized area (broken down into smaller units). This is done to characterize the event, classify it, and archive it for future comparisons with other events, whether ongoing, past, or expected in the near future.

GENERAL CONSIDERATIONS

For any given defined portion of territory, the principle of consistency of analysis criteria applies, meaning the analysis and characterization of events are conducted as described above, keeping both the time interval used and the geometric characteristics of the discretization into smaller territorial units constant.

For any given defined portion of territory, the principle of complete analysis of the phenomenon applies, meaning the analysis and study of it in the three dimensions of space and in time.
