POTENTIAL ENERGY VALUES AND FDC VALUES DISTRIBUTION IN THE HORIZONTAL PLANE

REPRESENTING RESULTS IN A MAP

SINGLE HYDROGRAPHIC BASIN

FIG_1: RIO MAGGIORE BASIN

FIG_2: HYPSOGRAPHY, ENERGY PROFILE AND FDC OF THE RIO MAGGIORE BASIN

In the chart it is possible to observe that in this case the two curves (FDC and POTENTIAL ENERGY PROFILE) are not coaxial so it could be affirmed that the drainage network is not in equilibrium but it is entirely ACTIVE. 

Infact reading the chart and applying rules explained previously it could be said that erosional processes characterize the entire slopes with particular intensity inside the altimetric band posted all around the maximum value of FDC.

FIG_3 CONTOUR LINE IN WICH POTENTIAL ENERGY ASSUMES MAXIMUM VALUE

Along the potential energy profile it was individualized the maximum value of the parameter and it was also extracted the altitude at wich this value appears (250/270 meters above the sea level). This data it is so represented in a map using at first the related contour line and then it was applied a buffering of 100 meters so to higthligth this isoline. 

FIG_4:  REPRESENTING FDC AND POTENTIAL ENERGY PROFILE. 

Inside the previous chart we could extract the range of altitude all around the maximum value of FDC curve and represent in the map only this parituclar altimetric band.

The result is that the contour line in wich it is possible to observe the maximum value of potential energy is not perfectly overlapped to contour line to wich relate the maximum value of FDC.

So, in general, it could be affirmed that in the case of a single hydrographic basin to represent results in a map help to understand the local evolutional trend of the hydrograpphy related to principle of coaxiality among the the two curves (FDC and POTENTIAL ENERGY PROFILE).

Both the two curves could change position during time and this aspect depend by the all factors previously listed (CLIMATE TECTONIC GEOMORPHOLOGICAL and ANTROPIC)

ADIACENTS HYDROGRAPHIC BASINS

It si important to specify that to obtain information or to hypothisize about regional evolution of hydrography we need to knows the evolutionary trend of differents adiacents basins so as the sample below.

FIG_4: ADIACENT BASINS ALONG SOUTH EAST SECTOR OF CIMINO MOUNTS.

(RIO MAGGIORE, RIO FRATTA, RIO RADICARE, RIO MICCINO, RIO PARANZA and MINOR BASINS IN ORTE SCALO VITERBO)

We are considering 6 adiacents basins posted along the volcanic slope of the MONTE CIMINO in LATIUM ITALY and these basins have differents dimensions so to have an overview about the evolutionary trend of this piece of territory.

FIG_5: EACH BASIN HAS HIS CONTOUR LINE IN WICH SURFACIAL RUNNIG WATERS REACH THE MAXIMUM VALUE OF POTENTIAL ENERGY.

In general it is possible to affirm that contour lines and altidude are differents basin to basin but there is continuity from south to north and infact the various contour lines of the basins are forming a sort of "BELT" in particular in the north of the investigated territory.

FIG_6: FDC VALUES MODEL OVERLAPPED TO POTENTIAL ENERGY MODEL

Overlapping the two models FDC and the POTENTIAL ENERGY model what it results indicates that there is an important area in intense erosion just upperhill to the belt of POTENTIAL ENERGY MAXIMUM so to reach the condition of equilibrium the hydrography of territory must modify the related networks.

In particular the area of intense ersosion  must shift or migrtate to downhill so to inglobe the potential energy line.

Infact the equilibrium condition foresee that this line must be perfectly overlapped to the  line indicating maximum values of FDC.

In these representations (FIG_5 e FIG_6) the line indicating the FDC maximum values is posted perfectly in the middle of the altimetric bands used to indicate the processes.

So considering that the solution is that erosional processes must migrate to downhill.

FIG_7: TECTONIC AND PROCESSES

So to interpret results an important help could be done by the structural model of the investigated area.

Comparing these two model so as in FIG_7 we could verify if and how tectonic influences evolutionary trend of the hydrography,
