Previous publications mainly deal with fluvial dynamics and continental sedimentation mechanisms  by means of archaeological records as a geoenvironmental marker. In such a manner  these studies are interdisciplinary essays. The kinds of topics revealed by these works are: 1) paleogeography of the riverbed network and definition of  the real sedimentation rates; 2) detailed stratigraphy and its relationships with geomorphology; 3) paleoenvironmental implications of the macroclimatic transitions; 4) detail morphological analysis; 5) aerophotogeologic interpretation; 6) basin and facies analysis; 7) eustacy and vertical movements; 8) process dynamics; 9) geoarchaeology; 10) historical topography problems; 11) various: e.g. archaeological hazard ; 12) today geoenvironmental approaches and problems.

All these themes can be grouped  in three main working lines: A) evolution of the alluvial plain hydrographic network; B) Holocene stratigraphy and geoarchaeology; C) tectonic activity and surficial deformations.

A) The Geomorphological Map of Po Plain (1997) does not exhaust the knowledge of the alluvial plain realm. Research and cataloguing of the Holocene (and Pleistocene, if outcropping) geomorphological units in the Po River alluvial Plain (mainly in Emilia-Romagna region) can explain the real evolution of  this physical landscape. It is possible to collect  all the morphological units  of the plain and try to identify them stating their own “paternity” and chronology. The characters of the human settlement through time and its related environmental impact rest on the hydrographic pattern history. The river-talweg evolution highlights the set of dynamics generating the landscape and its evolution. So this kind of study is a basic element for land-management although today it is perceived and considered exclusively in terms of  short period  hydraulic hazard. These themes are tightly linked to the next point ones.

B) The detail geological stratigraphy (i.e., in sedimentological terms, parasequences and even lower rank units) of the Holocene environments becomes aim and tool for glacial and postglacial processes and forms comparisons, and it can originate speculations concerning climate and soils evolution.  Therefore Geoarchaeology is mainly used by the writer as a low-cost but powerfull calibration tool for the sedimentary sequences. Really geoarchaeology has an intrinsic value too as  subsidiary discipline for archaeology, allowing both the reconstruction of the human societies environmental impact and a correct understanding and evaluation of their future trends.

This land-approach  also possesses other cultural values contributing both to the land-management and to cultural tourism exploitation and use of the Cultural Goods. This opportunity can not be misconsidered in a nation like Italy.

C) Previous arguments are directly related to the need and possibility of developing a better and more resolutive analysis of the uppermost part of the alluvial plain sedimentary cover and its reactions to the anthropogenic or natural environmental stresses.  Unpublished data, in fact, showed a series of  micro and/or macro-morphologies and phenomena whose interpretation could be equally related to tectonic behaviour, anthropogenic stress or climate change.                         

D) In a near future another field of application will have to be the geomorphological cartography of the Emilia-R. region that up to now is still completely lacking in the local scientific knowledge.

E) Other themes not yet included in the previous points (such as relationships between geostresses and human physiology) are already preserved in pectore because of their peculiar character.

In the last years three new kind of interestwere developed: 1) mountain slope deposits; 2) archaeo-seismological data in Emilia- Romagna region; 3) fossil fuel natural seeps and some related problems. In the latter case the “data-mining” work was mainly a large review of already available informations (concerning  Italy as a whole) often thought to be old and useless data. This kind of work  for the re-evaluation of old data was also extended to branches of  Physical Geography and Geomorphology (such as levelling surveys or historical maps even the pregeodetic ones) poorly or badly used (or misknown) to understand natural processes and phenomena over time scales longer than those usually considered today by means of expansive monitoring systems.

All those topics are poorly studied due to the real difficulties in  finding original data and to their highly time-consuming character. In fact, for example, the direct observation of stratigraphic details today is a very hard task due to the development of an exuberant  vegetational mantle in the mountain domain during the last sixty years and to the covering action made by the buildings in the plain lands. But this negative factor can be partially overcame, for example, by means of a continuous field-survey of building sites parallel to the archaeological controls practiced by the institutional offices.

This can provide a large data availability at a relatively low cost, although randomly distributed in space and time. But  on the other hand,  only  the extremely detailed examination of  the stratigraphic records  can reveal new  study aspects.
